ABSTRACT:
The invention relates to creating the illusion in a beverage dispensing device of liquid droplets that fill a drinking glass despite their appearance of rising from the drinking glass. The illusion is accomplished by oscillating the liquid and then applying a flashing light source whose frequency is slightly greater than the liquid oscillations. The enclosure and curtains of the invention allow the illusion to be viewed under certain conditions in room lighting. Also, under certain conditions an optical surface is attached to the enclosure which visually masks the ambient light.
